Boots Cash Chemists had just instituted a new way for its customers to buy certain
medicines. Shoppers could now pick drugs off the shelves in the chemist and then pay for them at the till. Before then, all medicines were stored behind a counter meaning a shop employee would get what was requested. The
Pharmaceutical Society of Great Britain objected and argued that under the Pharmacy and Poisons Act 1933, that was an unlawful practice. Under s 18(1), a pharmacist needed to supervise at the point where "the sale is effected" when the product was one listed on the 1933 Act's schedule of poisons. The Society argued that displays of goods were an "offer" and when a shopper selected and put the drugs into their shopping basket, that was an "acceptance", the point when the "sale is effected"; as no pharmacist had supervised the transaction at this point, Boots was in breach of the Act. Boots argued that the sale was effected only at the tills. ==Judgment==
